The purpose of this investigation was to determine the nature of the
chemical constituents of incense cedar bark with the hope that such an endeavor
would spur future research, development and use of a now neglected
natural raw material.
The bark from nine trees, which were separated into three age...
The purpose of this investigation was to determine the nature of the extractives from red alder bark in an effort to discover the materials which cause the red stain in red alder wood. Samples of bark and wood were obtained and successively extracted with hexane, benzene, ether, ethanol, and hot...
It is widely accepted among nursery producers that [Pseudotsuga menziesii (Mirbel) Franco] bark (DFB) is an excellent substrate for container production, hence its widespread use in Oregon and other regions where Douglas fir constitutes a significant portion of the forest products industry. Despite its widespread use, little information is available...
Phosphate, silicate and nitrate concentrations in the sea off
the coast of Oregon were determined to study their seasonal distribution
patterns. The water samples were collected monthly along the
east-west hydrographic line off Newport, Oregon, from the shore to
165 miles (310 km) offshore. The samples were analyzed by both...
This study focused on composition teachers in elementary and
secondary schools who researched their own teaching practices. Specifically, it
examined political implications of their work within the larger context of the
education hierarchy. Central to this examination were teacher-researcher (t-r)
perceptions of and interactions with other members of the education...
